Listing Worktrees

Listing Worktrees

Overview

List all autonomy worktrees in the repository, showing their branch, location, HEAD commit, and lock status. Helps users navigate and manage multiple parallel worktrees.

Core principle: Worktrees are working directories, not branches. This lists checked-out worktrees only, not all autonomy branches.

When to Use

Use this skill when:

• User runs /​list-worktrees command
• User wants to see which autonomy branches have active worktrees
• User needs to find worktree paths for navigation
• User wants to identify locked or stale worktrees

DO NOT use for:

• Listing all autonomy branches (use /​list-branches instead)
• Analyzing branch status or progress (use /​branch-status)
• Comparing branches (use /​compare-branches)

Quick Reference

Process

Step 1: Get All Worktrees

Retrieve complete worktree list from git:

# Get porcelain format for machine parsing
worktree_list=$(git worktree list --porcelain)

# Format:
# worktree /​path/​to/​worktree
# HEAD <commit-hash>
# branch refs/​heads/<branch-name>
#
# worktree /​path/​to/​another
# ...

Parse porcelain output:

# Extract worktree information
# Each worktree is separated by blank line
# Fields: worktree, HEAD, branch, detached, locked

# Example parsing with awk:
git worktree list --porcelain | awk '
  /^worktree / { path = substr($0, 10) }
  /^HEAD / { head = substr($0, 6); head_short = substr(head, 1, 7) }
  /^branch / { branch = substr($0, 8); gsub("refs/​heads/", "", branch) }
  /^locked/ { locked = "yes" }
  /^$/ {
    if (path != "") {
      print path "|" head_short "|" branch "|" locked
      path = ""; head = ""; head_short = ""; branch = ""; locked = "no"
    }
  }
  END {
    if (path != "") {
      print path "|" head_short "|" branch "|" locked
    }
  }
'

Step 2: Filter to Autonomy Worktrees

Keep only worktrees in .worktrees/​autonomy/:

# Filter parsed output to autonomy worktrees only
autonomy_worktrees=$(echo "$all_worktrees" | grep "\.worktrees/​autonomy/")

# Count autonomy worktrees
count=$(echo "$autonomy_worktrees" | grep -c "^" || echo "0")

if [ "$count" -eq 0 ]; then
  echo "No autonomy worktrees found."
  echo ""
  echo "Autonomy branches exist in main repository or without worktrees."
  echo ""
  echo "To create a worktree:"
  echo "  /​fork-worktree <strategy-name>"
  echo ""
  echo "To see all autonomy branches:"
  echo "  /​list-branches"
  exit 0
fi

Step 3: Format Output Table

Create readable table with worktree information:

Autonomy Worktrees:

Branch                    Path                                      HEAD       Locked
autonomy/​experiment-a     .worktrees/​autonomy/​experiment-a          a1b2c3d
autonomy/​experiment-b     .worktrees/​autonomy/​experiment-b          d4e5f6g    🔒
autonomy/​cdn-optimize     .worktrees/​autonomy/​cdn-optimize          h7i8j9k

Total: 3 autonomy worktrees

Column specifications:

• Branch: Full branch name (autonomy/<strategy-name>)
• Path: Relative path from repository root
• HEAD: Short commit hash (7 chars)
• Locked: 🔒 if locked, empty otherwise

Implementation:

# Print header
printf "%-25s %-41s %-10s %s\n" "Branch" "Path" "HEAD" "Locked"

# Print each worktree
echo "$autonomy_worktrees" | while IFS='|' read -r path head branch locked; do
  # Make path relative to repo root if absolute
  rel_path=$(realpath --relative-to="$repo_root" "$path" 2>/​dev/​null || echo "$path")

  # Lock indicator
  lock_icon=""
  if [ "$locked" = "yes" ]; then
    lock_icon="🔒"
  fi

  # Print row
  printf "%-25s %-41s %-10s %s\n" "$branch" "$rel_path" "$head" "$lock_icon"
done

Step 4: Provide Guidance

Add helpful navigation and management instructions:

To navigate to a worktree:
  cd .worktrees/​autonomy/<strategy-name>

To remove a worktree:
  /​remove-worktree <strategy-name>

To create a new worktree:
  /​fork-worktree <strategy-name>

Note: This lists worktrees only. To see all autonomy branches (including those without worktrees):
  /​list-branches

Additional context:

Locked worktrees (🔒):
- Cannot be removed without unlocking
- To unlock: git worktree unlock .worktrees/​autonomy/<strategy-name>

Important Notes

Worktrees vs Branches

This command shows worktrees, not branches:

• A branch may exist without a worktree (created via /​fork-iteration)
• A branch with worktree can also be checked out in main repo (though git prevents this)
• Use /​list-branches to see all autonomy branches regardless of worktrees

Example scenario:

Branches in repo:
- autonomy/​experiment-a (has worktree)
- autonomy/​experiment-b (has worktree)
- autonomy/​experiment-c (no worktree, created via /​fork-iteration)

/​list-worktrees shows: experiment-a, experiment-b
/​list-branches shows: experiment-a, experiment-b, experiment-c

Main Worktree

The main repository working directory is technically a worktree, but NOT listed here:

• We filter to .worktrees/​autonomy/ only
• Main repo worktree is not part of parallel agent workflow
• Focus on dedicated worktrees for clarity

Locked Worktrees

Worktrees can be locked to prevent accidental removal:

# Lock a worktree
git worktree lock .worktrees/​autonomy/<strategy-name>

# Lock with reason
git worktree lock --reason "Long-running experiment" .worktrees/​autonomy/<strategy-name>

# Unlock
git worktree unlock .worktrees/​autonomy/<strategy-name>

When locked:

• /​remove-worktree fails
• Must unlock manually before removal
• Useful for protecting important worktrees

Relative Paths

Paths displayed are relative to repository root:

• .worktrees/​autonomy/​experiment-a (not absolute /​home/​user/​repo/​.worktrees/​...)
• Easier to copy-paste for cd commands
• Consistent regardless of where command invoked

Common Mistakes

After Listing Worktrees

User can:

• Navigate to worktree: cd .worktrees/​autonomy/<strategy-name>
• Remove worktree: /​remove-worktree <strategy-name>
• View branch status: /​branch-status <strategy-name>
• Compare worktrees: /​compare-branches <strategy-a> <strategy-b>

Integration with Other Commands

Relationship to other autonomy commands:

Typical workflow:

# See which worktrees exist
/​list-worktrees

# Navigate to one
cd .worktrees/​autonomy/​experiment-a

# Work on iteration
/​start-iteration
# ... work ...
/​end-iteration

# Check all branches (including ones without worktrees)
/​list-branches

# Clean up worktree when done
cd <repo-root>
/​remove-worktree experiment-a

Empty State

When no autonomy worktrees exist:

No autonomy worktrees found.

Autonomy branches may exist in main repository or without worktrees.

To create a worktree:
  /​fork-worktree <strategy-name>

To see all autonomy branches:
  /​list-branches

To work on autonomy branch in main repo:
  /​fork-iteration <strategy-name>
  /​start-iteration
